 * applicable to non native fields. if a conditional callback is set on the FSTObjectInput, the callback
 * will be called before the object referenced by the annotated field is decoded. Allows to skip decoding of
 * objects partially to save CPU.

 * WARNING: can be used for unshared (cycle free) Objects only. In addition all classes contained in the
 * skipped subgraph need to be preregistered. So applicable rarely. See git issue #75
